This invention relates to means for dispensing predetermined quantities or amounts of granular or powdered material and its object is to provide a device of this character from which a measured amount of material may be discharged upon pressure being exerted on a proper part of the mechanism; to provide a device of this character with a n'ieasuring chamber which will be automatically filled immediately after the pressure sensing the discharge is released; and to provide a device of this character which may 3-3 of Fig. 2. Fig. 41 is an elevation of the measuring chamber. Fig. 5 and Fig. 6 are vertical sections of the discharge valve. Fig. 7 is a plan of the valve which controls the filling opening of the measuring chamber.

Similar reference characters refer to like parts throughout the several views.

This device is especially adapted for dispensing sugar, salt, ground coffee and such other commodities of granular form which will flow freely as hereinafter set forth. It consists generally of a main receptacle or container 1, preferably of glass, china or enameled ware provided with a cover 2, a pedestal 3 and a base l of any desired construction. A vent hole 5 may be located wherever desired or may be omitted. The bottom 6 of the container is provided with an aperture normally closed by the cover 7 of the measuring device which device rests upon the top plate 8 of the pedestal which plate also has an aperture but of somewhat smaller size than that of the bottom 6 so that the flange 9 at the upper edge of the measuring chamber 10 may rest on this plate 8.

The top plate of the measuring chamber has a normally open aperture 12 which permits the granular or powdered contents of the receptacle 1 to flow into the measuring chamber, and the outflow is normally pre vented by the small doors 1 3 which close the aperture 14 in the bottom of this chamber. The chamber is preferably provided with cars 15 in which the rods 16 are slidable, the

rods connecting at their upper ends to the cross bar 17 which carries a valve or closure 18. Light springs 19 (Fig. 4) may be employed to normally hold the valve 18 from over the aperture 12 in the top 7 to permit the contents of the container to flow down into the measuring chamber.

The small doors 13 connect to the rods 16 by means of the wire links 21 which are pivotally connected to both rods and doors. At the lower ends of these rods is a small plate, frame or table 20 adapted to receive a cup, spoon or other receptacle by means of which the small plate or table 20 may be depressed to lower the rods 16 and the doors 13% permit the contents of the measuring chamber to flow out. At the. same time, the valve or closure 18 is brought down to close the aperture 12 in the top plate 7 and thus prevents any more of the contents from flowing down into the measuring chamber. When the pressure of the cup or spoon is removed,

the springs 19 will close the doors '13 and open the aperture in the top plate 7 to pen mit the measuring chamber to be refilled.

I prefer to form the measuring;- chamber substantially elliptical in horizontal cross section to prevent it from turning. Small round wire springs 22 may be mounted on the pivots 23 of the doors 13 to assist in holding them closed.

It will be seen that the pedestal 3 is of suflicient height to permit the measuring chamber 10, rods 16 and table 20 to be interposed between the container 1 and the base 4.- and for the rods 16 and table 20 to move sufficient distances to carry out the functions of this device.

The details and proportions, the sizes of the filling and discharging openings may all be changed by those skilled in the art to which this device pertains without departing from the spirit of my invention as set forth in the following claims.

I claim 1. In a dispensing device, a container for material, a measuring chamber at the bottom thereof having a discharge opening, an apertured plate through which the material from the container may flow into the measuring chamber, a filler valve normally above the aperture in the plate and movable into contact with the said plate to close the aperture therein, hinged closing means for the discharge opening of the measuring chamber, a receptacle support movable relative to the measuring chamber, movement of the support in one direction opening the hinged closing means and movement thereof in the opposite direction closing the same, springs yielolably resisting downward movement of the support and means for operating the filler valve on movement of the receptacle support.

2. In a dispensing device, a container for material, a measuring chamber secured to the bottom thereof and having a discharge opening, an apertured plate through which material from the container may flow into the measuring chamber, a spring controlled closure normally removed from the aperture in the plate and movable to close the aperture in said plate, hinged means for closing the discharge opening of the measuring chamber, reciprocating means and resilient means tending to hold the same in uppermost position, connecting means between the reciprocating means and the hinged closing means of the chamber whereby downward movement opens the said closing means and reverse movement closes the same, means connected with the reciprocating means and the first named closure whereby downward movement operates the said closure to close the aperture in the plate.

3. In a dispensing device, a container for material having an aperturedbottom and a cover at the top, a measuring chamber supported in the said aperture in the bottom, the measuring chamber having an upper plate having a tiller opening through which material from the container may flow into the measuring chamber, a liller valve, a, spring yieldably holding the valve above the tiller opening, said measuring chamber having a discharge opening, a closure for the said discharge opening, comprising a pair o'l hinged plates meeting along a, central line, and reciprocable means adapted to simultaneously open the said closure and move the filler *alve down to close the filler opening.

4. In a dispensing device, a. container for material having an apertured bottom. a, standard supporting the same, a measuring chamber secured in the said aperture, a plate providing a cover tor the chamber and having a filler opening, a movable closure for the tiller opening, the said chamber having a discharge opening, a pair of hinged plates forming a closure for said opening, a pair of vertically reciprocable rods extending into the container, a spring for each rod tending to hold the same in uppermost position, a

table or plate attached to the lower end of the rods, a link coi'mecting each rod with one of the said hinged plates whereby downward movement of the rods may open the hinged plates and upward movement of the rods may close the hinged plates, a bar providing a connection between the rod ends and the movable closure for the tiller opening so arranged that downward movement of the rods causes the movableclosurc to cover the filler opening in the cover plate, said table providing a support for a receptacle into which material may be discharged on downward movement of the table, the standard being ot a length to allow the measuring chamber, rods and cooperative parts to be interposed between the container and supporting base.
